RICHMOND, Va. -- The jackpot for Wednesday night's Powerball drawing has jumped to $485 million, according to the Virginia Lottery. Lottery officials increased the jackpot based on strong Powerball ticket sales nationwide. Here in Virginia, lottery officials said they expected to sell about 1.5 million Powerball tickets on the day of the drawing. Even though no one matched all six numbers in Saturday's Powerball drawing, at least three lottery players in Virginia were happy Saturday night.

"Three Virginia tickets each won $10,000 in Saturday’s drawing. Those tickets were bought in Oakton, Portsmouth and Winchester," Virginia Lottery officials announced.  "If one ticket matches all six numbers, the winner will have a choice: either take the full $450 million jackpot in 30 annual payments or choose a one-time cash option of approximately $304.1 million before taxes."

Before you start thinking about what you'd do with the money, let's get serious: You're not going to win. Your chances of hitting the jackpot and taking home the entire Powerball winnings are extremely small -- one in 175 million, according to the Multi-State Lottery Association. So too are the odds that you'll take home a smaller prize of $1 million (one in 5 million) or even $100 (one in 12,000).

Still not convinced that your chances are slim? Here's the math -- from real mathematicians:

"If you just want a positive expected rate of return, then our results ... say to avoid Mega Millions and Powerball," wrote two Emory University professors, Aaron Abrams and Skip Garibaldi. Their 2010 paper "Finding Good Bets in the Lottery, and Why You Shouldn't Take Them" was published by The Mathematical Association of America.

It's more likely, for example, that you will die in a lightning strike (one in 136,000), or on board a plane (one in 8,000).

It's far more likely that you'll crushed by an asteroid that falls out of the sky (one in 700,000)

It's also more likely that a high school football player will play professionally (one in 1 million).

And it's far more likely that you'll be attacked by a shark (1 in 12 million).

There's nothing wrong with dreaming -- about quitting your job or that private island. But chances are, you're not going to win.
